FibX

Official DeFi execution MCP server for [Fibrous](https://fibrous.finance) aggregation across Base, Citrea, HyperEVM and Monad. 11 tools covering swap quotes, swaps with optimal routing, native and ERC-20 transfers, cross-chain portfolio with USD valuations, and Aave V3 supply/borrow/repay/withdraw plus live market APY/TVL/LTV. Quotes, transaction status and Aave markets need no wallet. Transactional tools carry `destructiveHint` and accept `simulate=true` for a preview that never broadcasts; Privy server wallets are created with a signing policy that caps per-transaction native value per chain. Local stdio, zero runtime dependencies: `npx -y fibx mcp-start`. In the official MCP Registry as `finance.fibrous/fibx` (namespace verified against the fibrous.finance domain). MIT.
